Introduction
Please read this manual completely from the first page to the last, to learn all the functions the
product offers. It is important to note that some of the operations may be explained in relation
to information in other chapters. By reading just one part of the manual, you may risk not
understanding the complete explanation of the function.
Before transmitting
There are many radio stations operating in proximity to the frequency ranges this product covers. Be careful
not to cause interference when transmitting around such radio stations.
■ Lightning
Any person is not safe outdoor during thunderstorm and lightning. This condition is getting worse if
somebody keeps a hand-held radio; chances of being hit by lightning are doubled since lightning may hit a
radio antenna as well. At this time, there is no hand-held radio having any kind of protection against lightning
current (which is higher than10 kA.). Note also that no car provides adequate protection of its passengers or
drivers against lightning as well. Therefore, Alinco will not take responsibility for any danger associated with
using its hand-held radios outdoor or inside the car during lightning.

■ Covering ranges
You may expect a range of approx.3km/2 miles or more at high-power when located on a at, noise-free
place like on a beach. However, it may vary drastically depending on how to wear and carry the radios,
surrounding locations/conditions and static noise levels (below or near power transmission lines), etc. In
urban areas with many buildings or inside a building, such covering range may become drastically short
even to several tens of meters.
